esc off problems?

[nadel]

my r-spec has 800 miles on it. have noticed that when accelerating with esc "off", from a dead stop, 25% of the time, i have a condition that appears to be complete shutdown of of fuel or electrics shutdown. condition last for no more than 2 secs. but obviously should not occur. have not contacted dealer yet. anone have same prob?

What makes you believe a fuel or electronic problem? Keep in mind the ESC apply's the rear brakes (even with the ESC botton off) and reduces power to the rear wheels by the cars ECU programming. I think what you may be experiencing is normal, but for most people including myself, undesirable.

yes, u are quite correct and i have been mulling over that very same thing. but...am still thinking..lol ...nevertheless, they did give us the on/off switch..why if it does not give the proper results.?

In my opinion, I think Hyundai did this to protect the drivetrain of the vehicle. That's a long warranty, and I don't think Hyundai wants to be doing warranty work on cars that have been pounded on etc.

If I turn off the ESC in my Sonata, it completely disables the traction control.

I know that the Genesis is not the only car that has this issue with it's ESC.

aaah thx for ur thoughts, and you most likely right, guess i will leave the esc switch alone for awhile. interestingly, if my memory is correct, with esc off and after i reach 20-30 mph and floor it, performance seems to be normal (that is awesome!)

At 20-30 MPH, what is different (performance-wise) than with ESC on?

Re: ESC off problems?

In the USA, the NHTSA requires ESC for safety reasons. Implementation has been phased in, but all cars manufactured after Sept 1, 2011 must have it. NHTSA literature suggests that complete compliance testing was not required until the above date, so that ESC systems implemented before that date may not meet all current standards. Therefor it is possible that pre-2012 Genesis models had slightly different ESC operation that 2012+ models.
http://www.nhtsa.gov/DOT/NHTSA/Rulemaking/Rules/Associated Files/ESC_FR_03_2007.pdf

As we all know, even when the ESC is turned off by the driver switch, it is not completely disengaged. The NHTSA recognized that when a car is stuck in sand, gravel, etc, it is useful to at least party disengage the ESC, so that is the only reason why they agree to let you partially turn it off. Even when it is shut off, the NHTSA requires that the ESC automatically come back on next time the car is started.

Since the requirement for ESC mandated by the NHTSA is for safety reasons, there could be legal liability issues if a car allowed the driver to completely disengage the system (remember the lawsuits concerning the Ford Explorer and Chevy Corsair poor handling?). More than likely, manufacturers are going to err on the side of safety than on the ability to do street racing, in order to avoid compliance issues with NHTSA and legal liability complications in the case of an accident.

Also keep in mind that most of these type systems on a car are manufactured by outside suppliers and are a part of the ABS system and integrated with ECU (although it is possible that Hyundai makes their own, or owns a subsidiary that makes them). The Genesis seem to have a higher percent of parts made by outside suppliers than most other Hyundai vehicles.

thats a good question, and difficult to answer, but acceleration (esc-off) seems to be faster. but that is just a feeling. faster than with esc on.

Re: ESC off problems?

thx mark. matter of fact i remember corvair quite well, never owned one for various reasons but always felt that people had handling problems because of too low tire pressure. btw, i traded in 2005 crysler 300c (with 22,80 miles) and with esc off never had a single problem with "hesitation" and performance seemed to be faster (subjectively).

 

[nadel]

it is really WONDERFUL how the government looks after and takes so much care, and even does our thinking for us, isn't it? anyway will someone try it and see what happens to their r-spec?

As I mentioned in post above, even though some cars had ESC before 2012 Models, there was no compliance testing before Sept 2011, and before that time the ESC may have been less obtrusive than it would be now on a new 2012 300C. Or maybe Chrysler just did it better.

mark, point taken thanks

I read an interesting tidbit from a review of the 2013 Coupe and it stated that there were three modes for the ESC/TCS.

1. Fully on - the default.
2. TCS Disabled, ESC Enabled - Single short push of ESC Off button.
3. TCS/ESC fully Disabled - Push and Hold the ESC Off button for 4 seconds.

I plan to try this in my 2011, but have no expectation of it working. It may be worth a try in the 2012 and see what happens....

 

[nadel]

hmm interesting RW, ill try that.

 

[nadel]

rwlewis..i held switch for 10 sec (in park and drive) and at first i thot the esc WAS disabled. seemed to have no problems stalling on accleration . however, when i floored it at stop light and wheels started to spin the tc kicked again and it was as i said before seemed like electric or gas was shutdown. interestingly, when i tried to use cruise control, message popped up saying "conditions not met" so it did not work. thx for suggestion tho.

Something is not right with your car. I would take it to the dealer and show them the issue. When I was at the dealer I had the sales manager drive mine since I was complaining about the sluggish tranny. We did a couple of launch tests with the ESC on and off. The car is a rocket with ESC off and I've never had it stall like you say. If your dealer won't launch it with the ESC off, take it to one that will. These cars were not meant to be driven like granny wagons. If the dealer gives you a hard time for beating the car, ask them if they've you seen the YouTube video of the R-Spec tearing up the track.

On the sedan to completely disable the traction and stability control, you have to pull the fuse. There is a thread on this.

 

[nadel]

RSPEC.. thx for info, problem is as if the brakes locked (or gas was shut off) for 1-2 secs when i floor it from stop. happens everytime (apparently when wheels begin to slip) of course i am talking about when i have esc in off condition. it does seem tho when i am at or above 20mph and floor it no problems occur. or at least i dont remember the brakes locking up. oddly, if i am in "sport" mode it works as i think it should and have not noticed any problems at all.

 

[nadel]

thx gambler ll check it out if other rspec owners can floor it at stop light with esc off and the cars runs properly then i do have some problem.

Hmm, this is reminiscent of how it worked on my 2008 300C/SRT8
Press the button and release cut the system back, but not off.
Hold the button down and it had a little electronic bell that would chime when it deactivated.

Without the Traction Control the thing was a total beast to drive and took every bit of your concentration to keep the wheels from spinning.
Fun, but pretty much useless for driving.
The thing would smoke the rears at 50+ and start drifting...white knuckle style.
